Deployment Success

Hello, I’m working with Rest API, to “automate” some operations with Ansible, trought URI Module and Jinja2. I need to create a Project, and set permission to a specific user. How can i do this with API V3? I can add user to a Project, but i can’t set the Role.. When i check trought the Web Interface, i see the user without role. Thanks!

Hi, everyone I’m trying to use LCM to update firmware of host machines on my cluster. It all went well until the post action phase. Error message said: ‘Operation failed. Reason: LCM failed performing action reboot_from_phoenix in phase PostActions on ip address xx’. I searched the KB and found KB9177，but it’s about ‘Mixed Hypervisor cluster‘, my cluster uses solely AHV so it doesn’t applied. Anyway I still tried to follow the KB9177’s suggestion and upgraded my cluster’s foundation to 4.5.3 and retried the LCM firmware update process on another host but still got the same ‘ LCM failed performing action reboot_from_phoenix’ error. I used the workaround provided in that KB to make the affected two hosts’ CVM out of maintenance mode. It works and the cluster is back to normal. Then I logged on to the affected hosts’ IMM and found out that actually the primary IMM2 firmware has already been updated by the LCM( the backup IMM2 firmware is not upgraded), and when I go to the LCM section

Hello, for LCM updates I see that pre-checks require DRS in fully automated mode. It’s possible to perform LCM updates without DRS in fully automated mode (in the event that a customer does not have DRS in his licenses) ? Thanks Manuel

Hello. I faced with limitation of number VMs in API reply. There is option “length” which can be added to request, but max value is 500 (I got it into experiments). We have around 1000 VMs in our environment. Is there solution?

Hello, We have a cluster with 4 nodes and I will perform the update from 5.9.4.2 to 5.10.10.1. a some minutes ago, I see that my cluster have a disk space problem and the resilience board is red with the “not resilience” information. In this case I will have a problem when perform the AOS upgrade? I not have time to resolve the space issue now…  Please, send me any information.

is there any way to created additional users in nutanix move? -jai

I’m trying to setup a new bridge (br1). After ssh to the Nutanix AHV,  I continue with input “ssh root@xxx.xxx.xxx.xxx” to get to the CVM,  it ask me for a password.  Is there a way to change/ continue with a different logon name as well at that? The password I input is being denied due a different username for the CVM.

Hello, comunity I’m been trying to figure out why the configuration with RF2 & N+1 reserves more capacity than just RF2. I understand that with RF2 all the data is duplicated along the cluster and the failure of one node is tolerated. In my scenario I have a 3-node cluster with 34TiB of effective capacity, so with RF2, I would have only 17TiB, everything is clear until that point. But the extent store assuming RF2 & N+1 gives me 11.3TiB, which is 1/3 of my available capacity. So...the question is: If I reserve capacity, by tripling all the data, that is for tolerate 1 additional node failure besides the 1st one (tolerated by RF2)?  A silly conclussion would be that with RF2 & N+1 the cluster is able to tolerate 2 nodes and continue operating just with one node, but I know that is not posible. So, why assuming RF2 & N+1 reserves more TiB’s than just RF2? Please, I would appreciate the help. Thanks in advanced!

I have a W2k19 VM I created as a patched image. Idea is to patch it monthly. Shut it down and clone it. Then sysprep the clone and copy the disk to the Image Service. Then I can create VM’s off of it. I will repeat the colne after patching the ~master image monthly in order to keep a patched disk ready to spin up VM’s from. We are using AHV, version 5.10. Mt question is the “CLONE” a full, independant copy of the VM ? TIA -S

Hi community, I’m fairly new to interacting with Nutanix for automation and was hoping my VM build task would be a simple process but I’ve hit a wall with the guest tools install. I’m building a RDS environment where I need as little human interaction as I can get to make administration easier so I’m building my host VM using SCCM. I’ve multiple good reasons for approach but its mainly in support for application deployment via happening at build time. I’ve tried to install the guest tools manually but I believe they are failing due to the files being copied from a mounted ISO which has some dynamically created certificates involved so this isn’t going to work. I can see the ISO can be mounted using the API calls but every reference I’ve seen looks to need  a username/password passing in the script and I’m not overly keen in hard coding creds into script. Most of what i’ve seen is a few years old so I wondered if there has been any changes to the approach to mounting guest tools? It

Giving thought to change your replication factor from 2 to 3? What are the impacts and things to consider?   First, let’s take a look at what replication factor is. Redundancy factor is a configurable option that allows a Nutanix cluster to withstand the failure of nodes or drives in different blocks.   By default, Nutanix clusters have redundancy factor 2, which means they can tolerate the failure of a single node or drive.  So RF3 means cluster can tolerate the failure of 2 nodes or drive… Basic Maths isn’t it?   Redundancy factor 3 has the following requirements: Redundancy factor 3 can be enabled at the time of cluster creation or after creation too. A cluster must have at least five nodes for redundancy factor 3 to be enabled. For guest VMs to tolerate the simultaneous failure of two nodes or drives in different blocks, the data must be stored on containers with replication factor 3. Controller VMs must be configured with a minimum of 28 GB(20 GB default+8 GB for the featur

Dear all We run 2 Clusters with each 3 ESXi and 2 AHV Storage-only Nodes successfully.  Now I want to get rid of VMWare, but all vms were built with vmware, of course I see them in prism. Did anyone ever just deinstall ESXi and replaced it with AHV in a running environment? Alternatively I could move all urgent vms to one Cluster and than install Nutanix from scratch and afterwards migrate the vms to the Nutanix only Cluster. thanks and best regards, Claudia

Can any one list out how many types of Foundation are there eg Foundation Pro, bare metal ..etc. 

What are the 3rd party snapshots? Third-Party snapshots are generated by a third-party backup tool over API calls to our storage. The Nutanix system does not manage this type of snapshots and will keep the snapshots until it receives a deletion instruction from the third-party tool.   The NCC health check aged_third_party_backup_snapshot_check checks the cluster for dangling third-party backup snapshots that may be present for a protection domain. If a third-party backup snapshot has existed in the system for longer than the specified period, this check will raise an alert. These backup snapshots are snapshots that are generated from 3rd party backups (Veeam, Commvault, Rubrik, HYCU, etc.).    The check passes if third-party backup snapshots are not present in the cluster longer than the configured threshold. The default threshold is 7 days, but this threshold value can be modified. The threshold can range from 1 day to 365 days. For more information, examples and solution check out K

Hi Folks,   I have a few machines I would like to convert from IDE to SCSI.   I understand this can be done with acli. The procedure is to clone the ide disk and replace it for the VM.   nutanix@cvm$ acli vm.disk_create <vm_name> clone_from_vmdisk=<vmdisk_UUID> bus=scsi   However, I’d like to do this in PowerShell given I’ve already started developing down that track. I have PowerShell cmdlets to snapshot and shutdown the VM which are recommended steps before performing this task.   I didn’t see a cmdlet to perform the clone and replacement, so I turned to the REST API. I am fairly new to Nutanix to I wanted to get some feedback on whether this is the right approach or at least that its not going to break anything other than my test VM. $uri = "https://$ntxCluster/api/nutanix/v2.0/vms/$($vm.vmid)/disks/attach"$body = '{"uuid":"abcdefg-08h3-4i44-95j0-kl44m82no758","vm_disks":[{"vm_disk_clone":{"disk_address":{"device_bus":"SCSI","device_index":123}}}]}'$headers=@{}$headers.A

As the title said, does anyone know about this interface is used for?
